Platform: Raspbian GNU/Linux 11 (bullseye) on Raspberry Pi 2

Node Version: 22.11.0

MagicMirror² Version: 2.29.0

Description: After upgrading MagicMirror from v2.28.0 to v2.29.0 my web interface won't display anything. Turning on developer tools displays missing /env subpath resulting in an exception in loader.js / main.js and subsequent loading.

Steps to Reproduce: I use a nginx webserver, which uses a reverse proxy on /apps/MagicMirror to redirect it to hostname:8080. My config.js has the reverse proxy included.

let config = {
	address: "0.0.0.0",
	port: 8080,
//	basePath: "/",
	basePath: "/apps/MagicMirror/", 	// The URL path where MagicMirror² is hosted. If you are using a Reverse proxy
					// you must set the sub path here. basePath must end with a /
	...
};

Expected Results: As for previous versions socket.io uses the basePath to establish socket connection between client and server. The initial loading for loading environment variables should, too.

Actual Results: MagicMirror loading fails. As a workaround I modified loader.js to

  const res = await fetch(`${location.protocol}//${location.host}/` + config.basePath + `/env`);

in order to make my application work again. Probably needs further refinement and exception handling.
